Bought a brand new 572XP from a guy (not a dealer) to replace my old Stihl 044. Went through 2 tanks and it was running great. Then it wouldn't started while hot. Thought I flooded it trying to start it, did what I do on every Stihl I own which is starting with the throttle wide open to clear the cylinder when flooded. I was able to get it started but it was running rich, real rich and no power.
Searched online for help, pressure/vacuum tested carb and it passed. Decided only thing to do was replace the carb (auto tune carb costs $200 - make no mistake I am complaining about the cost of the carb). Decided I didn't want or need the dealer to charge me for programming the new carb so I pulled the electronics off of the old carb and put on the new carb. Started first pull and it ran like a champ. Reset the auto tone by cutting an 8' length of a log.
Pulled it out again a couple of weeks later (gas was getting old by this point). Pulled it many times and it would not start, but I could smell gas. Dumped the gas, put fresh gas in, cycled the purge bulb multiple time to try to clear the lines of the bad gad. Tried to start with throttle wide open to clear the flood. It started, same deal running rich and no power.
The only thing that seemed to be consistent before running really rich is me clearing the flooded engine by trying to start it with the throttle wide open. Just plain stupid if that can ruin a carb, but this is my first Husqvarna. Anyone experience the same problem or have advise here it is much appreciated.
